Have there been additional studies to investigate the
relationship between seropositivity and infectivity. In other words what is the
probability of obtaining an infection from eating pork tenderloin (or another
eatable tissue) from a seropositive pig?
Also was there an age related pattern of infection in the population. Were
older sows more likely to be infected than younger grow-finishers?

Are there published studies of Trichinella prevealnce in eatable
tissues purchsed from supermarkets? Which tissues are more likely to contain
the parasite ? This would be an interesting study if it has not been done.
